回到过去还是去往未来
到目前为止,时空旅行还只是停留在幻想之中。不过也有人提出过这样一个问题,如果可以做到时空旅行,你是想回到过去还是想去往未来呢?
如果我们以现在为基点,那么去往未来应该比回到过去更靠谱。比方说我现在穿越到未来了,看到在未来n年后BTC涨到了1百万美元,那么我现在就应该趁BTC只有6000多的时候狂买BTC。可如果反过来,虽然我现在没有BTC,但我穿越回到过去,比方说我回到了2010年BTC分文不值的时候,我狂买BTC。然后我再回到现在,赫然发现我现在突然有好多BTC了。这听上去似乎是不太可能的,因为这相当于现在无中生有变出一堆BTC啊。再举一个例子,如果可以回到过去不让你父母认识,那现在也就没有意义了,因为你不存在了。
这么看来,回到过去应该是个伪命题。过去的事情都已经发生完成了,无法更改了,回去了也没用。这或许也告诉我们,与其为过去后悔,不如展望未来,把握当下。
